Henry wrote 4z² - z² as 4. Are 4z² - z² and 4 equivalent expressions?

1 answer:

7 0

No, a lone variable has an invisible one in front of it, So 4z (can’t put the top number sorry) So 4z - z would equal 3z

Choose one of the factors of 6x^3 + 6

ivanzaharov [21]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

$6x^3+6$

Now, by factorising , we get

$6x^3+6\\=6(x^3+1)$

Now, we use the formula i.e.

$a^3+b^3=(a+b)(a^2-ab+b^2)$

By using this, we get ,

$6(x^3+1)\\=6(x+1)(x^2-x+1)$

So,

$(x+1) \text{ is the factor of }6x^3+6.$

Don’t know how it looks hope it’s better

sveticcg [70]

Answer:

80 ounces

Step-by-step explanation:

In one pint, there is 16 ounces. Thus, if she picked five pints, 16 × 5 = 80 ounces.

Another way to solve this problem is by setting a proportion.

$\frac{2cups}{1pint} = \frac{10cups}{5pints}$
$\frac{8ounces}{1cup} \frac{80ounces}{10cups}$

Therefore, the answer is 80 ounces.
